Field Pioneers Elucidate Wetland Functions from a Multidisciplinary Perspective Wetland ecosystems maintain a fragile balance of soil, water, plant, and atmospheric components in order to regulate water flow, flooding, and water quality. Marginally covered in traditional texts on biogeochemistry or on wetland soils, Biogeochemistry of Wetlands is the first to focus en - tirely on the biological, geological, physical, and chemical processes that affect these critical habitats. Integrates concepts from soil and plant sciences, chemistry, biology, ecology, and environmental engineering This book offers an in-depth look at the chemical and biological cycling of nutrients, trace elements, and toxic organic compounds in wetland soil and water column as related to water quality, carbon sequestration, and greenhouse gases. It details the electrochemistry, biochemical processes, and transformation mechanisms for the elemental cycling of carbon, oxy - gen, nitrogen, phosphorus, and sulfur. Additional chapters examine the fate and chemistry of heavy metals and toxic organic compounds in wet - land environments. The authors emphasize the role of redox-pH condi - tions, organic matter, microbial-mediated processes that drive transformation in wetlands, plant responses and adaptation to wetland soil Features: conditions. They also analyze how excess water, sediment water, and at - mospheric change relate to elemental biogeochemical cycling. • Discusses the role that sediment redox- pH conditions play on metal specia - Provides an ideal teaching text or professional reference for tion, availability, and transformations those involved in ecological restoration, water quality, • Examines the role of microbial ecological engineering, and global climate change processes in sulfate reduction, denitiri - fication, and methane production Delivering an in-depth scientific examinination of the natural processes that occur in wetland ecosystems, Biogeochemistry of • Examines the adaptation of wetland Wetlands comprises a key perspective on the environmental plants to varying anaerobic soil impact of pollutants and the role freshwater and coastal conditions S ee wetlands play in global climate change. • Presents results from research studies w conducted on the Florida Everglades h a and Louisiana’s Mississippi River deltaic t yo plain fo u r S E I ’ X G r a C N e t w LU U m w S P w IV i .
